ADU details

ADU legality: allowed

Stateallowed (Rhode Island accessory-dwelling framework (RIGL §45-24-37(j) and §45-24-73, as amended by H 7062 / S 2998 of 2024)) — All 39 RI municipalities must permit ADUs by-right on every single-family lot; HOA-restriction preemption. RI counties are judicial-only since 1846 — no county zoning.
Countyallowed (Providence County (judicial only)) — Providence County has no land-use authority; jurisdiction is the Town of Scituate.
Cityallowed (Town of Scituate Code of Ordinances Appendix A (Zoning); Hope Village Overlay District; Chapter 4 (Buildings & Building Regulations)) — Hope is a Village Overlay District inside the Town of Scituate (no separate municipal government); permitting is administered by Scituate Building Official Michael DiOrio at Town Hall, 195 Danielson Pike, North Scituate, RI 02857.

Scituate permits ADUs by-right under Appendix A conformed to RIGL §45-24-37(j). Approximately 14,436 acres of the town are PWSB-owned Scituate Reservoir watershed — PWSB watershed-protection review is a hard prerequisite for parcels in the W (Watershed) zone or its buffers.

Permitting process

Typical duration90 days
Backlog14 days
  1. Confirm Appendix A base district + Hope Village Overlay (~5d)
    Identify the Scituate Appendix A base district plus Hope Village Overlay District requirements; verify the RIGL §45-24-37(j) 20,000 sqft minimum lot for by-right ADU. Hope Village Overlay design standards may apply to ADUs visible from the village street grid (massing, setback, materials).
  2. Submit OWTS application to RIDEM (~70d)
    Scituate explicitly requires an approved OWTS (On-site Wastewater Treatment System) application and plan before the building permit process begins — there is no public sewer in Hope village. Engage a RIDEM-licensed designer; OWTS site evaluation, design, and approval typically run 8-14 weeks.
  3. PWSB watershed-protection review (if applicable) (~21d)
    If parcel is within or adjacent to W (Watershed) zone or PWSB-owned land in the Scituate Reservoir watershed (~14,436 acres of the town), file Providence Water Supply Board watershed-protection review concurrently. Hope village sits along the Pawtuxet River downstream of the reservoir but the watershed overlay still applies to many parcels.
  4. Pre-application contact with Building Official (~5d)
    Contact Scituate Building Official Michael DiOrio at (401) 647-5901 / mdiorio@scituateri.org or Clerk Calista McDermott (cmcdermott@scituateri.org). The town reports that 'building permits for new construction generally take 2 weeks for processing' but a Hope-village ADU's full schedule (with OWTS and PWSB) realistically extends to ~90 days end-to-end.
  5. Apply via permits.ri.gov (~1d)
    Apply via the RI statewide e-permitting portal at permits.ri.gov, selecting 'Town of Scituate' / 'building department'. Attach OWTS approval (or pending RIDEM acknowledgement), site plan, floor plan, elevations, and Hope Village Overlay design narrative if visible from the village street.
  6. Administrative ADU review (~14d)
    Administrative ADU review under Scituate zoning. Hope Village Overlay design standards reviewed for any ADU visible from the village street grid; by-right ADUs avoid Zoning Board hearing.
  7. Plan review (uses outside trade inspectors) (~14d)
    Plan review by Scituate Building Department. Note: the office uses outside trade inspectors — there are no resident electrical/plumbing/mechanical inspectors on staff, which can extend trade-inspection scheduling vs. Smithfield/Burrillville.
  8. Pay statewide-formula fees + RIDEM + PWSB (~1d)
    Pay statewide-formula permit fees per 510-RICR-00-00-21 (~$19-23 per $1,000), plus RIDEM OWTS review fee per 250-RICR-150-10, plus PWSB watershed review fee where applicable. Scituate does not assess a town development impact fee.
  9. Construction inspections
    Foundation, frame, OWTS install (RIDEM-witnessed separately), rough MEP, insulation, and final. Outside trade inspectors require advance scheduling.
  10. Certificate of Occupancy (~5d)
    Issued by Scituate Building Official after final inspection passes; OWTS performance-of-work letter must be on file from RIDEM.

Viability (permitted uses)

  • Long-term rental: yes Long-term rental of ADU explicitly permitted under RIGL §45-24-37(j); RI HOA preemption (§45-24-73) voids conflicting covenants.
  • Short-term rental: with-restrictions Scituate regulates STRs separately from ADU permitting; check town STR ordinance and any HOA covenants.
  • Office rental: with-restrictions Detached office rental requires home-occupation permit; watershed-overlay parcels have additional impervious-surface limits.
  • Home office: yes Home occupation permitted with restrictions on signage and customer traffic.
  • Studio / workshop: yes Personal artist studio is a permitted accessory use; village-overlay aesthetics may apply.
  • Agriculture: with-restrictions Watershed-overlay parcels limit agriculture to protect drinking-water source.
  • Relative support: yes Family-occupied ADU explicitly permitted; statewide §45-24-37(j) by-right treatment.

Rhode Island state — ADU law and programs

State ADU law

Rhode Island enacted statewide ADU preemption in 2024 through H 7062 (chief sponsor Rep. June Speakman and colleagues; co-sponsored in the Senate as S 2710), which amended the Zoning Enabling Act (Title 45, Chapter 24). Municipalities must permit ADUs by-right on any lot containing a single-family dwelling, subject only to uniform minimum standards set by the statute. One of the most ADU-friendly state statutes in the country as of 2025.

State HOA preemption

R.I.G.L. § 45-24-73 explicitly voids homeowners' association, condominium association, or similar private-covenant restrictions on ADUs when those restrictions conflict with the statute's ADU minimums. The preemption is framed as a public-policy void, meaning the offending covenant is unenforceable rather than simply regulated. Pre-existing ADU-friendly covenants remain valid (the statute only void conflicting restrictions). Applies to all common-interest communities governed by the Rhode Island Condominium Act (R.I.G.L. Title 34, Chapter 36) and Rhode Island Condominium Ownership Act (Title 34, Chapter 36.1), as well as HOAs in planned-community subdivisions.

  • R.I.G.L. § 45-24-73 (HOA preemption clause added by H 7062 (2024)) — Provides that private covenant restrictions imposed by condominium associations, homeowners' associations, or similar residential property governing bodies that conflict with the ADU provisions are void as against public policy. Drafted broadly — covers declarations, bylaws, rules and regulations, and recorded covenants.

State financing programs

RIHousing, the state's housing finance agency, operates an ADU financing program built around the FHA 203(k) loan product. Covers attached and interior ADUs for both purchase and refinance. Detached ADUs are NOT eligible. Requires mandatory homebuyer education, use of an FHA-approved 203(k) consultant, and a RI licensed and insured contractor. No state-specific grant program for ADUs is in effect as of 2026-04-21; the federal 203(k) rails are the production vehicle.

State housing programs

Rhode Island does not currently operate a single statewide pre-approved-ADU-plan catalog (as California's CalHFA and Washington's Commerce plan libraries). Implementation of the 2024 ADU law is happening municipality-by-municipality, with the Executive Office of Housing (EOH) coordinating technical assistance. Providence published a citywide ADU Guide (February 2025) as the leading model; East Providence adopted a conforming ordinance in 2024; South Kingstown published regulations in 2024. RIHousing runs the ADU financing side (see stateFinancing).

Federal (United States) — ADU-relevant rules and programs

Federal ADU law

The United States has no federal statute that directly regulates accessory dwelling unit entitlement or design. Land-use authority over ADUs resides with states and local governments under the traditional police power. Federal engagement is limited to financing (Fannie/Freddie/FHA/VA/USDA), flood insurance (FEMA/NFIP), and discretionary housing programs (HUD), which are recorded in sibling sections of this file.

Federal financing programs

Federal housing-finance agencies and GSEs set nationwide underwriting rules that govern whether an ADU can be financed, appraised, and counted toward mortgage qualifying income. The relevant actors are Fannie Mae, Freddie Mac, FHA (HUD), VA, and USDA Rural Development.

Federal tax credits

There is no ADU-specific federal tax credit. ADUs may incidentally qualify for existing federal energy-efficiency and clean-energy tax credits when the ADU construction includes qualifying measures.

Federal housing programs

HUD administers several discretionary programs that can fund ADU-related activity at the grantee's election, but none is an ADU-specific program.
